PPO/PPE is a crystalline thermoplastic with excellent heat distortion resistance but unable to be melt processed. The methyl substituted version is considerably less crystalline and can be melt processed in blends with other thermoplastics.
Below are a list of key properties of PPO/PPE
¡¤ Good dimensional stability.
¡¤ Good electrical properties.
¡¤ High heat distortion temperature above 100¡ãC (up to 195 ¡ãC).
¡¤ Modified PPO blends are soluble in moderately polar solvents
¡¤ Hard, rigid, strong, reasonably tough and low creep.
¡¤ Being a blend it is opaque.
¡¤ Good dimensional stability.
¡¤ Good electrical properties.
¡¤ High heat distortion temperature above 100¡ãC (up to 195 ¡ãC).
¡¤ Modified PPO blends are soluble in moderately polar solvents.
¡¤ Suffer the same problems of oxidation and UV ageing as polystyrenes unless suitably stabilised.
¡¤ UV exposure causes server colour changes.
Applications
The good water, heat and electrical resistance make PPO/PS ("Noryl") suitable for hot water applications but many of the applications are in instrument housings and internal components in electrical equipment.
We are able to help design and custom any size or shape from your measurements, a drawing or existing sample. Plastic injection molding and Precision CNC machined are available from OTEM Plastic Company, provide us CAD drawing , application detail and touch medium , then we can advise the best proposal of custom plastic parts. Lead time of mold will cost about 20-30 days , production upon sample approved .
